Translation of "Invariably" in French

It's emotion that invariably wins.

les émotions gagnent invariablement.

They will invariably lead to mistakes.

elles vous conduiront forcément à faire des erreurs.

And the answer, that I almost invariably get is --

Et la réponse que je reçois presque invariablement est :

Such a person invariably expends his physical energy more slowly.

Ce genre de personne consomme son énergie physique plus lentement.

Not thinking before he speaks, he invariably proceeds to stick his foot in his mouth.

Ne réfléchissant pas avant de parler, il doit invariablement se mordre les doigts.
